The Best Flutter Responsive UI Pattern

Today I want to go over my solution to provide Sizing information at a base widget level so it can easily be incorporated into any architecture. This tutorial will not be to make a UI appear exactly the same on every screen size. It will actually be the opposite. I would like to provide myself with enough information to intelligently modify my UI’s appearance based on screen sizing. I want to do this at an view (screen) level as well as a widget level.

The Problem

The question that we’re answering today is “How can we provide all relevant information at a widget level to modify our UI?”.

The Solution

Provide a BaseWidget that gives you the opportunity to build your UI using custom ScreenInformation compiled by you specifically for that goal. Instead of making use of the the MediaQuery in every widget and view file we will build it into the BaseWidget and build SizingInformation object that will be available to every widget using the BaseWidget.

Let’s go over what we’d like to provide in the SizingInformation and also why we would want this information:

Orientation: We want to be able to easily determine which layout to show based on the current orientation. Possible values Landscape and Portrait.
DeviceScreenType: This will reflect the Screen Type we are displaying on. Not the physical device screen but the display type .i.e. Mobile, Tablet, Desktop
ScreenSize: This reflects the total size of the current screen the app is being displayed on
LocalWidgetSize: This reflects the bounds that the current widget is being drawn in. It will allow you to make smart UI choices at the widget level as well, such as hiding text in a Icon+Text widget and instead increasing the icon size for much smaller screens.

Implementation

To implement the functionality we will make use of two Flutter provided sets of Functionality.

MediaQuery: This provides us with some valuable information, most importantly the Orientation and ScreenSize. We’ll use this to determine the first 3 info points mentioned above.
LayoutBuilder: This widget provides us with a builder that also gives us BoxConstraints which indicate to use the Bounds the current widget is taking up. We’ll use the bounds from the Builder to create our LocalWidgetSize value and pass that back.

With that in mind lets start the implementation.

SizingInformation

Before we can create the SizingInformation we need an enum that represents our DeviceScreenType. Under the lib folder create a new folder called enums, inside create a new file, device_screen_type.dart (naming can definitely change).

enum DeviceScreenType {
  Mobile,
  Tablet,
  Desktop
}

Then create a new folder under lib called ui and inside create a new file called sizing_information.dart

import 'package:flutter/widgets.dart';
import 'package:response_architecture/enums/device_screen_type.dart';
class SizingInformation {
  final Orientation orientation;
  final DeviceScreenType deviceType;
  final Size screenSize;
  final Size localWidgetSize;
  SizingInformation({
    this.orientation,
    this.deviceType,
    this.screenSize,
    this.localWidgetSize,
  });
  @override
  String toString() {
    return 'Orientation:$orientation DeviceType:$deviceType ScreenSize:$screenSize LocalWidgetSize:$localWidgetSize';
  }
}

Now that the model is done lets setup the builder that we’ll use to build our UI for us.

UI Architecture

We’ll start by creating a StatelessWidget under the UI folder called BaseWidget. It will take in a Function that returns a widget, that function will be named builder. The parameters to the function will be the BuildContext and the SizingInformation. For the build method, we will execute that builder and return the widget it produces.

import 'package:flutter/material.dart';
import 'package:response_architecture/ui/sizing_information.dart';
class BaseWidget extends StatelessWidget {
  final Widget Function(
      BuildContext context, SizingInformation sizingInformation) builder;
  const BaseWidget({Key key, this.builder}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    var sizingInformation = SizingInformation();
    return builder(context, sizingInformation);
  }
}

Then we can set up a simple home_view to see how we’ll make use of this. Under the UI folder create a new file called home_view.dart

import 'package:flutter/material.dart';
import 'package:response_architecture/ui/base_widget.dart';
class HomeView extends StatelessWidget {
  const HomeView({Key key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return BaseWidget(builder: (context, sizingInformation) {
      return Scaffold(
          body: Center(
        child: Text(sizingInformation.toString()),
      ));
    });
  }
}

Before we test we’ll set up a package that helps us to easily test our layouts. This will be used in development for quick UI testing only, the majority of your testing should still be on the real devices, if not possible the emulator or the Web to easily test all sizes. We’ll add the Device Preview package to the pubspec.

device_preview: 0.1.9-beta

Then in the main file we’ll follow the instructions, wrap the App in Device preview and supply it with the appBuilder from the package. Make sure your home file looks like below.

void main() => runApp(
      DevicePreview(
        child: MyApp(),
      ),
    );
class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      builder: DevicePreview.appBuilder,
      title: 'Flutter Demo',
      home: HomeView(),
    );
  }
}

You should be seeing a preview like below if you’re using an Android emulator. I’d recommend spinning up a Tablet sized AVD but a basic emulator works fine for me when it’s sized to be as big as possible.
This is image title

If you click on the top left corner on the cog icon you can rotate the device, change the device and see how the UI responds in milliseconds. Now lets move on to gathering the information and populating the SizingInformation.

Populating the Information

We’ll start off by passing in our Orientation.

var mediaQuery = MediaQuery.of(context);
var sizingInformation = SizingInformation(
  orientation: mediaQuery.orientation,
);

Then we’ll determine the DeviceType with a top-level function stored in the ui_utils.dart file under the utils folder. The way we determine the device we’re on is through the width of the device. Since the mediaQuery.size doesn’t return the size of the physical device, we have to make sure we’re using the correct dimensions. We determine the screen type by the width of the device. Since the width of the screen will reflect differently based on the orientation we will use either the width or height depending on the orientation. When the device is in portrait we can use the width to determine the width of the device. When it’s in landscape we have to use the screen height to determine the width of the device.

DeviceScreenType getDeviceType(MediaQueryData mediaQuery) {
  var orientation = mediaQuery.orientation;
  double deviceWidth = 0;
  if (orientation == Orientation.landscape) {
    deviceWidth = mediaQuery.size.height;
  } else {
    deviceWidth = mediaQuery.size.width;
  }
  if (deviceWidth > 950) {
    return DeviceScreenType.Desktop;
  }
  if (deviceWidth > 600) {
    return DeviceScreenType.Tablet;
  }
  return DeviceScreenType.Mobile;
}

In the BaseWidget we can now get the devicesScreenType from using this function and passing in the MediaQuery. We can also pass the screen size.

var mediaQuery = MediaQuery.of(context);
var sizingInformation = SizingInformation(
  orientation: mediaQuery.orientation,
  deviceType: getDeviceType(mediaQuery),
  screenSize: mediaQuery.size,
);

If you reload your code now and change the sizing to an ipad Air2 you’ll see DeviceType.Tablet on the screen, the correct orientation etc. The only thing left is the LocalWidgetSize. And for that, we’ll require the LayoutBuilder mentioned in the beginning.
Instead of executing the builder function and returning that we’ll return the LayoutBuilder as the root widget and for it’s builder we’ll execute and return the function passed in along with the BoxConstraints converted into a Size object.

Widget build(BuildContext context) {
  var mediaQuery = MediaQuery.of(context);
  return LayoutBuilder(builder: (context, boxSizing) {
    var sizingInformation = SizingInformation(
      orientation: mediaQuery.orientation,
      deviceType: getDeviceType(mediaQuery),
      screenSize: mediaQuery.size,
      localWidgetSize: Size(boxSizing.maxWidth, boxSizing.maxHeight),
    );
    return builder(context, sizingInformation);
  });
}

If you reload the code now you’ll see the correct sizing information required. If you want to see how we build a responsive UI using this setup subscribe to the FilledStacks YouTube channel, to see how I build a responsive UI.

Google's Flutter 1.20 stable announced with new features - Navoki

Flutter Google cross-platform UI framework has released a new version 1.20 stable.

Flutter is Google’s UI framework to make apps for Android, iOS, Web, Windows, Mac, Linux, and Fuchsia OS. Since the last 2 years, the flutter Framework has already achieved popularity among mobile developers to develop Android and iOS apps. In the last few releases, Flutter also added the support of making web applications and desktop applications.

Last month they introduced the support of the Linux desktop app that can be distributed through Canonical Snap Store(Snapcraft), this enables the developers to publish there Linux desktop app for their users and publish on Snap Store. If you want to learn how to Publish Flutter Desktop app in Snap Store that here is the tutorial.

Flutter 1.20 Framework is built on Google’s made Dart programming language that is a cross-platform language providing native performance, new UI widgets, and other more features for the developer usage.

Here are the few key points of this release:

Performance improvements for Flutter and Dart

In this release, they have got multiple performance improvements in the Dart language itself. A new improvement is to reduce the app size in the release versions of the app. Another performance improvement is to reduce junk in the display of app animation by using the warm-up phase.

sksl_warm-up

If your app is junk information during the first run then the Skia Shading Language shader provides for pre-compilation as part of your app’s build. This can speed it up by more than 2x.

Added a better support of mouse cursors for web and desktop flutter app,. Now many widgets will show cursor on top of them or you can specify the type of supported cursor you want.

Autofill for mobile text fields

Autofill was already supported in native applications now its been added to the Flutter SDK. Now prefilled information stored by your OS can be used for autofill in the application. This feature will be available soon on the flutter web.

flutter_autofill

A new widget for interaction

InteractiveViewer is a new widget design for common interactions in your app like pan, zoom drag and drop for resizing the widget. Informations on this you can check more on this API documentation where you can try this widget on the DartPad. In this release, drag-drop has more features added like you can know precisely where the drop happened and get the position.

Updated Material Slider, RangeSlider, TimePicker, and DatePicker

In this new release, there are many pre-existing widgets that were updated to match the latest material guidelines, these updates include better interaction with Slider and RangeSlider, DatePicker with support for date range and time picker with the new style.

flutter_DatePicker

New `pubspec.yaml` format

Other than these widget updates there is some update within the project also like in pubspec.yaml file format. If you are a flutter plugin publisher then your old pubspec.yaml is no longer supported to publish a plugin as the older format does not specify for which platform plugin you are making. All existing plugin will continue to work with flutter apps but you should make a plugin update as soon as possible.

Preview of embedded Dart DevTools in Visual Studio Code

Visual Studio code flutter extension got an update in this release. You get a preview of new features where you can analyze that Dev tools in your coding workspace. Enable this feature in your vs code by _dart.previewEmbeddedDevTools_setting. Dart DevTools menu you can choose your favorite page embed on your code workspace.

Network tracking

The updated the Dev tools comes with the network page that enables network profiling. You can track the timings and other information like status and content type of your** network calls** within your app. You can also monitor gRPC traffic.

Generate type-safe platform channels for platform interop

Pigeon is a command-line tool that will generate types of safe platform channels without adding additional dependencies. With this instead of manually matching method strings on platform channel and serializing arguments, you can invoke native class and pass nonprimitive data objects by directly calling the Dartmethod.

There is still a long list of updates in the new version of Flutter 1.2 that we cannot cover in this blog. You can get more details you can visit the official site to know more. Also, you can subscribe to the Navoki newsletter to get updates on these features and upcoming new updates and lessons. In upcoming new versions, we might see more new features and improvements.

You can get more free Flutter tutorials you can follow these courses:

What is Flutter and why you should learn it?

Flutter is an open-source UI toolkit for mobile developers, so they can use it to build native-looking** Android and iOS** applications from the same code base for both platforms. Flutter is also working to make Flutter apps for Web, PWA (progressive Web-App) and Desktop platform (Windows,macOS,Linux).

flutter-mobile-desktop-web-embedded_min

Flutter was officially released in December 2018. Since then, it has gone a much stronger flutter community.

There has been much increase in flutter developers, flutter packages, youtube tutorials, blogs, flutter examples apps, official and private events, and more. Flutter is now on top software repos based and trending on GitHub.

Flutter meaning?

What is Flutter? this question comes to many new developer’s mind.

humming_bird_dart_flutter

Flutter means flying wings quickly, and lightly but obviously, this doesn’t apply in our SDK.

So Flutter was one of the companies that were acquired by **Google **for around $40 million. That company was based on providing gesture detection and recognition from a standard webcam. But later when the Flutter was going to release in alpha version for developer it’s name was Sky, but since Google already owned Flutter name, so they rename it to Flutter.

Where Flutter is used?

Flutter is used in many startup companies nowadays, and even some MNCs are also adopting Flutter as a mobile development framework. Many top famous companies are using their apps in Flutter. Some of them here are

Dream11

NuBank

Reflectly app

Abbey Road Studios

and many more other apps. Mobile development companies also adopted Flutter as a service for their clients. Even I was one of them who developed flutter apps as a freelancer and later as an IT company for mobile apps.
